SPINNING-JACK.

Specification of Letters Patent No. 9,858, dated July 19, 1853.

T 0 all whom it may concern:

Be it known that I, JOHN JACKSON, of Lawrence, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Jacks for Spinning Woolen or other Yarn, by which theSame are greatly Simplified; and I hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe annexed drawings, making part of this specification.

The nature of my invention consists in a simple and effectual method offorming the cops and bobbins, and also in an improved method ofstripping the spindles preparatoryto winding on the thread.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

Figure 1 represents a side elevation of my self-operating jack, with thecarriage taken out. Fig. 2 is a rear elevation of the head stock. Fig. 3is a section on A B of Fig. 1, showing the carriage and the partsconnected therewith. Fig. 4 is a front elevation of the head stock. Fig.5 a plan of the same. Fig. 6 is a detached view of the former is" andthe parts by which it is actuated. Fig. 7 is a plan of the carriage.Fig. 8 is a view of the hook o.

My machine is of the class in which the head stock is placed behind theroller beam. The rovings are given out from the drawing rollers in thecustomary manner. No further description is therefore required of thispart of the mechanism, and I will confine my description to thoseportions of the machine which I consider as new and to the partsimmediatelv connected therewith.

The movements of the machine may be divided into two classes: firstly,those governing the motions of the carriage; secondly, those connectedwith the formation of the cops, and the stripping of the spindles. Thesemovements I will now proceed to describe.

A is the containing frame of the head stock; B, the roller beam; C, thecarriage, the wheels D of which run upon the ways E. The carriage istaken out in the following -'1nanner:a is the driving shaft, upon whichis secured the bevel gear 7', which through the intermediate bevel gears76 and Z, drives the gear 192-, and clutch m, which are fast together,and loose on the shaft 7. They are made to revolve with the shaft,

' secured thereto.

however, by the clutch 0, which revolves with the shaft 11,, by means ofa feather, while it slides horizontally upon it. The clutch 0 is movedby the lever 11-. The end of the lever u is secured to one end of alever 8, which has its fulcrum at t, Fig. 1. Upon the other end of thislever s is a semi circular piece '0, which is struck by the piece 2,Figs. 1 and 2, upon the carriage, when the latter has reached the end ofits motion, by which means this end of the lever s is depressed and theother end, bearing the clutch lever to, is raised. The clutch 0 is thusunshipped from m, and the shaft 1?. ceases to turn, as also the scrollp, which is This scroll carries the cord 70 which after passing over thestationary guide pulley Z is secured to the carriage at m As the shaft12 revolves, the cord 70, is wound upon the scroll p, and the carriageis taken out. When the clutch lever a is raised by the upward motion ofthe lever s, the former falls into a notch in a pendant hook i similarto that represented in Fig. 8, and the lever u is thus held up, theclutch 0, m being open, until the carriage again comes in, when thefoo-t 70 projecting from the carriage, strikes the point 2, of the hook2"", and the clutch lever 10 is thus disengaged from the notch 1 of thehook 2"", and the lever it falls, the clutch 0, m, is closed, and motionis again communicated to the shaft 71 and scroll 79, for the purpose oftaking the carriage out as before.

The carriage is taken in in the following manner: Upon the shaft (4 arethe three pulleys Z), 0, and (Z. Pulley b, is fast to the shaft; C isloose thereon, and the pulley (Z, the gear 6, and clutch f, are fasttogether and loose upon the shaft a. Also loose upon this shaft is theclutch (Z, and gear 2", which are fast together. The gear 2" through theintermediate wheels a, I), gives motion to the cog wheel C, which isfast to the scroll CZ, and runs with it loosely upon the shaft 12. Thecord r which is wound around the scroll d, passes thence to thecarriage, where it is secured to the pin 8 and thus whenever the belt isshipped upon the pulley (Z, and d is in clutch with f, the cord W,

is wound upon the scroll cl, and the carriage is taken in. This movementof the belt shipper and clutch is effected as follows: The belt shipper25 slides in bearings e upon the frame of the head stock. To the beltshipper Z is jointed a lever '0 which is pivoted to the frame of themachine at 10 From the other end of this lever is suspended by the rod mthe lever 2, the weight of which rests constantly upon the lever Q2 andthus tends to slide the belt shipper in its bearings (Fig. at). Thismotion of the belt shipper is prevented by the catch m, which is pivoted'to it at the point 6 At the other end of the catch 05, is a notch whichrests against the stationary pin 3 projecting from the frame of themachine. The belt shipper is thus held stationary, and the belt runsupon the fast pulley b.

The following device is made use of to move the belt shipper when it isdesired to shift the belt upon the pulley (l: The worm s" is attached tothe shaft a, Fig. 4-, and engages with the cog gear 9", which runs upona pin 0 projecting from the frame of the machine. Pendant from the saidpin is the finger w, and from the gear 1'' projects the pin '0, which,as it revolves, carries around the finger a, which striking against theprojection cl, upon the catch a, raises the latterover the pin 3 andthus the belt shipper is left free to move under the action of theweighted lever 2, as before described. The belt is returned to the fastpulley b at the proper time, in the following manner: 6 is a rollerrunning freely upon a pin projecting from the cog gear 7". To theextreme end of the lever e, and beyond its fulcrum a is hinged upon apin 9 the upright lever 71. which rests in a guide i projecting from theframe of the machine. Upon the top of the lever 714, is a semicircularpiece 70 As the belt is now upon the pulley cl, the gear 0, which isfast to the pulley, engages with the wheel j, which is thus driven untilthe roller 6 at the appointed time strikes the semicircular head of thelever 7L4, Fig. 1, and de presses the short arm of the lever .2, andraises the long arm, and thus through the rod 09 the horizontal arm ofthe lever "0 (Fig. 4c) is raised and the belt shipper i moved, throwingthe belt upon the fast pulley Z), and withdrawing the catch :2: untilits notch again falls over the pin 7 which holds the belt upon thepulley 6, until, by the revolution of the pin 0), the catch :0, is againreleased at the appointed time and the belt is shipped as before to thepulley d. At the instant that the roller 6 has passed the head of thelever M, and shifted the belt as just described the gear j,no longerdriven by the gear 0, stops, and in order that its momentum may notcarry it beyond the point at which it was when the belt was shipped theroller 6 is made to strike against a brake or stop R, hinged to the longarm of the lever .2, at the point 1", and passing up through the guide7, and thus the motion of the gear j, is instantly arrested in such aposition that when the belt is again shipped upon the pulley (Z, and thecog gear y" is set in metion the roller 70 shall be in position todepress the head of the lever Z, and thus operate the stripping andbuilding wires in a manner to be described. The brake B, being hinged tothe lever 2, is dropped out of the way of the roller 0 when the lever z,is depressed and at the instant that motion is again communicated to thegear j, by the shifting of the belt.

Motion is given to the spindles as follows: The shaft a is geared to theshaft g, by the wheels a (Z and intermediate wheels 6 Upon the shaft 9is the band wheel 9', carrying the cord P, which, after passing oncearound the cylinder 71, and over the guide pulley 9 upon the carriage,is conducted over the pulleys h and i back to the band wheel wheel 9".Thus when the driving band is upon the fast pulley b and the shaft a isin motion the band wheel 9, upon the shaft 9, is revolved, and also thedrum it, from which pass the bands 6 to the wherves of the spindles.During the return of the carriage the spindles receive a much slowermotion, which is produced in the following manner: The clutch (Z ismoved by the bent lever I). The long arm of this lever is held up byresting in a notch (1) in the pendant hook 0), see Fig. 8. lVhenreleased from this notch the lever 7) gives way to the pressure of thespring 0, and is depressed, carrying with it the lever e, pivoted at i,and connected at its other extremity with the lever f, which moves theclutch 9, so that the depression of the lever 7) moves simultaneouslythe clutches (Z and g. The band be ing now upon the pulley (Z, the cogwheel 0 attached to it, drives the gear j, which is loose upon the shaftProjecting from the wheel j is the roller (4, which as the formerrevolves strikes against the point 2 of the pendant catch 41, and knocksthe latter from beneath the lever b, which falls from out the notch 1 ofthe lever 11, and thus at the instant that (Z is made to clutch with f,(by which means, through the gearing i, a, b, 0", and scroll (Z thecarriage is brought in) the gear j is clutched with the shaft y by whichmeans, through the band wheel 9', a much slower motion is communicatedto the spindles to wind on the thread as the carriage comes in. Thelever Z) is again raised and lodged in the notch 1 of the hook e, forthe purpose of opening the clutches f, d, and g, h, in the followingmanner: H, Figs. 1 and 2, is an arm projecting from the carriage, havingat its advanced end aninclined plane Z, which passes beneath the lever bwhen the carriage comes in and raises it, by which means, through theconnections already described, the clutches f, d, and g, h, aresimultaneously opened. The scroll (Z having brought in the carriage,ceases to revolve, and the band wheel g no longer receives its slowmotion from the gear y". At the same instant that this is performed thebelt is shipped upon the fast pulley b, and the band wheel 9, throughits connections with the shaft a, commences its rapid motion necessaryon the going out of the carriage for the 1erforming of the spinningoperation, the clutch m 0 having been closed at the same instant by therelease of the lever a from the notch 1 in the hool: i

The operation of building the cop is performed as follows: L, Figs. 1and 6, is a sliding frame running in ways m, upon the carriage. Upon theupright bars L of this frame, as ways, moves the former Upon the uppersurface of the former s", which is curved, so as to give the requisiteshape to the bobbin, rests the vertical rod to, which is connected withthe faller wire, as will be hereafter explained. To the former arecommunicated two motions, the one horizontal with the frame L in itsways pa the other a vertical motion upon the upright arms L. The firstof these motions is communicated as follows: Beneath the carriage andalong its whole path is laid the rack f", which engages wit-b the cogwheel 9 upon the short shaft it upon the carriage. Upon the same shaftis the pinion 2', which engages with the rack 7' upon the sliding frame.As the carriage is taken in the cog wheel 9 engaging with the stationaryrack f is revolved and the pinion 2' upon the same shaft is revolvedalso. This pinion engaging with the rack 7', gives motion to the slidingframe L, in a direction contrary to that in which the carriage itselfmoves, and-thus the former Z2" traverses a distance equal to its lengtheach time the carriage comes in, and raises and depresses the rod 4.0,in accordance with the contour of its upper surface. The vertical motionof the former is communicated as-follows1 Q is a screw which revolvesfreely in the boss of, projecting from the sliding frame L. This screwworks in a nut 0, projecting from the former 7c, in such a manner thatas the screw is turned the former is raised. At the lower eiitremity ofthe screw Q is the ratchet wheel 7). 0 is a pawl hinged to the carriage,and so placed that upon each motion of the carriage L in its ways theratchet wheel shall be brought in contact with the pawl and turn therebya distance equal to the length of one tooth. The former is thusgradually raised the operation of building the cops goes on.

The bobbins z are stripped in the following manner: 72*, are armsattached to the back of the carriage, in which is boxed the shaft 02. sis an upright rod pivoted to the carriage at g and pressed toward theshaft 00 by the spring r 8 is a bent arm upon the shaft 00, having acatch (4 which passes under a notch t in the lever s, which prevents theshaft m from being revolved by the action of the weight y attached tothe arm w, secured to the shaft 03. The arms a of the stripping wire 2are also attached to the shaft 40. Z, m, Fig. 1, connected together bythe rod 2), and pivoted near their centers at the points a and 0,receive at the appointed time a limited vibratory motion, in manner andfor the purpose which will now be explained. When the carriage is fullytaken out, the belt being thrown upon the pulley (Z, and thegear j beingin the position shown in Fig. 1, the gear 6 drives the cog wheel j, andthe roller k upon an arm projecting from the gear j, strikes the top ofthe lever Z, which is thrown back, and the top of the lever m, by itsconnection with the former is thrown forward toward the carriage, andthe arm Q upon the lever m strikes against the pin r, made adjustable ina projection from the lever s, by which means the lever s is forced in,and the arm 5*, upon the shaft 90, escapes from the notch t in the levers, and the weight y is permitted to revolve the shaft :0, by which meansthe arms a, and the stripping wire .2, are thrown up and the bobbins arestripped.

The arms a, and the stripping wires which they carry are depressed andheld out of action-while the operation of spinning is going on in thefollowing manner: at, are arms pivoted to the top of the carriage, atthe point w, ig. 1,) and connected to the arms 20 by the wires o Whenthe carriage comes in, the arms a passing under the roller beam B, arepressed down, and with them the arms a, by which means the shaft :0 isrevolved, and the catch upon the curved arm 5*, passes beneath the notchin the lever s, and the stripping wire is held out of the way of thethread until the proper time arrives for the bobbins to be stripped, andthe catch (0 upon the curved arm .9, is relieved, as before described,by the piece Q striking the pin 1, and moving the lever s.

In the description of Fig. 6 has been shown the manner in which the copis formed, and I will now describe the method by which the faller wireis moved, and held out of the way of the spindles while the operation ofspinning is going on.

6*, Fig. 7, is another shaft upon the can riage, running in the arms 9which also carry the shaft 02', and immediately in front of the latter,attached to this shaft, are the arms u which carry the building wire m.Z is another arm attached to the shaft 6*, and resting upon the rod 10,while the carriage is taking in, by which means the requisite motionis'given to the building wire m to enable it to form the bobbin asrequired. s is another arm upon the shaft 27, to which is attached thewrist 20*. To this latter is attached the vertical rod 02 see Figs. 3and 7, having a pin g through it near its lower extremity. When thecarriage has finished taking in, the pin has passed up the inclinedplane 2*, upon the lever z, seen in dotted lines in Fig. 1, and theupright rod 02*, is thus raised, and with it the crank or wrist w, bywhich means the shaft 6, is revolved, and the building wire m is raised.The latter is kept in the position it now occupies until the carriage isagain taken out in the following manner: a, is a metallic sliding restattached to the base piece 6 which slides freely in the trough 0 Thesliding stop (6 is of the form seen in Figs. 1 and 7. (Z is a notch ordepression in which the crank '10, when it is raised, as beforedescribed, is permitted to rest. At such time the piece a is thrown intothe position immediately beneath the crank w, in the following manner:a, is a weight suspended from the sliding rest a by the cord F, by whichmeans, when the crank w, is raised, the rest if, is drawn up beneath it.When the carriage has taken out and reached the end of the stretch andthe building wire is required to descend for the urpose of forming thecop, the curved head 9 of the lever m, strikes against the projection7?, from the base of the sliding rest and the latter is thrown back intothe position seen in Fig. 7. The crank w then drops the arm Z upon therod w, and as the carriage takes in, the motion of the building wire m,is governed by the rod w, which receives its motion directly from theformer Operation: We will suppose the carriage to be taken in. Theprojecting bar H in front of the carriage having, in the manner alreadydescribed, raised the lever Z) into the notch 1 of the hook o, therebyopening the clutch f, (Z, and also through the rod 6 connecting theclutch levers Z) and f, opening the clutch g, h, whereby the motion ofthe scroll CZ, which takes the carriage in, is stopped, and the gear y",is unshipped from the shaft 9, the foot 70 at the same instant strikingagainst the point Q of the hook 2' by which means the latter is thrownback and the clutch lever 20, is permitted to drop out of the notch inthe hook i The long arm of this clutch lever being thus depressed, theclutch m 0, is closed and the shaft n, and scroll p, commence to revolvefor the purpose of taking the carriage out, the belt having the instantbefore been thrown upon the fast pulley b, by the motion of the shipper6 as already described, by which means the shaft a is again set inmotion and the spindles are turned rapidly while the carriage is takingout, the band wheel 9 now receiving its motion from the shaft a throughthe intermediate gear 5 0 as already described, the rovings, as beforestated, being new delivered in the customary manner from the drawingrollers. The carriagev continues to take out until it reaches theposition shown in Fig. 1. The

' project-ing bar Q, from the bottom of the carriage now strikes thesemicircular piece upon the end of the bar .2, the other end of which,being thereby raised, el vates the clutch lever w, Fig. 4, which opensthe clutch m, 0, and stops the motion of the shaft n and scroll p, andthe outward motion of the carriage ceases. At the appointed time, whensufficient twist has been put into the yarn, the belt is shipped on tothe pulley (Z, by the operation of the pin 1), in the wheel 9", andmotion is thus communicated to the gear j, which (being new in theposition represented in Fig. 1, the brake R having been withdrawn by themoving of the shipper and the dropping of the lever 2) is revolved. Theroller 72 now depresses the head of the lever Z, which through itsconnection with the lever on releases the stripping wire, which isthrown up by the action of the weight y, as already described. Thesliding piece 0. being pushed back at the same instant by the projectingnose g, of the lever m, the lever Z", upon the shaft 2?, falls upon therod to, which rests upon the surface of the former 7c". The belt havingnow been shifted to the pulley (Z, and the roller a upon the gear 7',having knocked the hook b from beneath the lever Z), the clutch f, CZ,is closed and the scroll cZ, commences to take the carriage in. Theclutch g, 77/ being now closed, the gear j drives the shaft g, and withit the band wheel 9, by which means the slow motion is given to thespindles while the carriage takes in, for the purpose of winding on theyarn, the former 7c, traversing a distance equal to its length beneaththe rod w, as the carriage takes in, to regulate the form of the bobbinin manner already described, the former being raised on each stretch bymeans of the screw, ratchet, and pawl, represented in Fig. 6, to allowfor the increase in size of the bobbin. When the carriage coming in hasnearly reached the end of its course, the pin g projecting from the rod00, attached to the crank 20*, (Figs. 3, 7,) encountering the inclinedplane a, of the lever .2, as already described, the arm 11*, and with itthe building wire, is raised. The levers a, at the same time passingbeneath the roller beam are depressed and carry with them the arms u,and the stripping wire prepara tory to commencing another stretch, theprojecting arm H opening the clutch f, d, and stopping the scroll cl,which takes the carriage in, the foot 76, upon the carriage in manneralready described closing the clutch m, 0, that the scroll p, may takethe carriage out when the roller 6*, upon the gear 7', has shifted thebelt upon the fast pulley b, and the rapid motion of the spindlescommences.

It will be seen that by means of the combinations above described I amenabled to effect with unerring precision all the various intermittentand complicated movements required from machines of this description,and with an amount of machinery less than half of that heretoforeemployed for the same purpose.

The gear j, with the aid of a few rollers and other simple appendages,operates the winding on mechanism, raises the stripping wire anddepresses the building wire, which operations it performs in the properorder by a simple motion of revolution, which it receives from the gear0, and then shifts the belt upon the fast pulley b, the wheel j, itselfbeing left in the precise position necessary for the re-performance ofthe same operations when it is again set in motion.

I do not claim stripping the bobbins preparatory to winding on: Neitherdo I claim raising the former by a horizontal screw, givilpg motion toan inclined plane beneath it; ut

What I do claim and desire to secure by Letters Patent is- 1 The stop Bin combination with the be withdrawn by the mechanism which shifts thebelt at the instant the gear 9', is again set in motion.

2. Operating the winding on mechanism, raising the stripping wire, anddepressing the building wire, in the proper order, and then shifting thebelt on to the fast pulley at the close of these operations, by means ofa single cogged gear, in combination with the tappet placed upon itsside, the whole arranged and combined in the manner substantially asspecified.
